REFRIGERATION FIRM CHOOSE ATLANTICS' HIGH EFFICIENCY BOILERS TO TEST NEW PRODUCTS
Lancashire based Atlantic Boilers have installed their high efficiency boilers at Star Refrigeration's' testing plant in Glasgow. Star, one of the UK's largest independent industrial refrigeration engineering companies, are launching the "Indigo Chiller" an energy efficient, low noise chiller solution early next year.
Douglas Hamilton is the Chief Engineer of Star Refrigeration. He approached Atlantic Boilers to develop a boiler test rig.
'We required a specially produced rig with very high efficiency, flexible boilers - reflecting our 'Indigo-chiller' performance - and which could be conveniently accommodated at our adapted premises at Westway near Glasgow Airport".
The specially produced skid consists of two boilers (each nominally rated at 500kW) together with associated mixing chambers, pumps and control valves. The test water is pumped through the boilers in series to raise the water temperature going onto the 'Indigo-chiller'. The water first passes through an NA-R 500 boiler with a gas-fired analogue modulating burner with efficiencies achieving 84% GCV. The water then flows through an R22-500 year-round condensing boiler with a gas-fired speed inverter controlled modulating burner to give precise temperature control at efficiencies from 92% GCV to 99% GCV throughout the year. Effectively the R22-500 is the lead boiler performing the function of always matching the chiller load.
Andrew Cowan - Commissioning Adviser, reports that the Atlantic Boilers system is giving great service.
"We want to use the facility to give customers the opportunity to see each 'Indigo-chiller' run-tested and put through its paces before shipment to site and also to carry out these tests with minimum impact on the environment."
The NA-R 500 can be fired by either natural gas or diesel oil. The R22-500 can be fired by many fuels including rape seed oil, natural gas, LPG, diesel oil and kerosene - plus other carbon-neutral fuels. This fuel flexibility will be of great value in the coming years.
